Unformatted text preview: n g cos = n a , or = cos 1 n a n g = cos 1 1 1 . 52 = 48 . 9 . The index of refraction for air is taken to be unity. (b) We now replace the air with water. If n w = 1 . 33 is the index of refraction for water, then the largest value of for which total internal reection occurs is = cos 1 n w n g = cos 1 1 . 33 1 . 52 = 29 . ....
